[0040] The box body 4 is provided with a driving member in communication with the air inlet cavity 41; the driving member and the activity frame 32 are provided with a linkage mechanism.

[0041] Specifically, the air conditioner filter element with fragrance of the embodiment, after the external air enters the air inlet cavity 41, then enters the filter element assembly from the air inlet face 12, a part of the air directly blows out from the air outlet face 11 to the air outlet cavity 42, another part of the air enters the accommodating cavity 13 from the bottom wall of the accommodating cavity 13, and drives the first fragrance 14 to volatilize, so that the air with fragrance is blown out from the opening of the accommodating cavity 13 to the air outlet cavity 42, so that the air conditioner filter element has fragrance;

[0042] In addition, the adjusting plate 3 is tightly attached to the surface of the air outlet face 11, and the gas of the air outlet face 11 can only enter the air outlet cavity 42 through the ventilation hole 31 of the adjusting plate 3; the activity frame 32 and the adjusting plate 3 can be moved by the driving member and the linkage mechanism, so that the coincidence degree of the ventilation hole 31 and the opening of the accommodating cavity 13 can be adjusted, so that the opening size of the accommodating cavity 13 can be adjusted, so that the volatilization degree of the first fragrance 14 can be adjusted.

[0043] The filter of the embodiment, the driving member comprises a cylinder shell 5, a piston 51 movably arranged in the cylinder shell 5, and a reset spring 54 arranged in the cylinder shell 5;

[0044] One end of the piston 51 is provided with a boss portion 52; the boss portion 52 separates the cylinder shell 5 into an upper cylinder cavity and a lower cylinder cavity; the reset spring 54 is arranged between the bottom of the boss portion 52 and the lower cylinder cavity; a first air guide pipe 55 is arranged between the top of the upper cylinder cavity and the air inlet cavity 41; after one end of the piston 51 protrudes out of the lower cylinder cavity, a hinged portion 53 is formed; the linkage mechanism is arranged between the hinged portion 53 and the activity frame 32.

[0045] The filter of the embodiment, the linkage mechanism comprises a hinged seat 6, a first connecting rod 61, a second connecting rod 62, a third connecting rod 63, a fourth connecting rod 64, and a connecting strip 65; the hinged seat 6 is arranged in the air outlet cavity 42;

[0047] The movable frame 32 is provided with a sliding block 66; the air outlet cavity 42 is provided with a sliding groove 67.

[0048] Specifically, when the filter works normally and the air inlet amount is the minimum value, the air pressure generated in the air inlet cavity and the air cylinder upper cavity is equal to the elastic force of the reset spring 54 in the air cylinder shell 5; at this time, the air vent of the adjusting plate 3 completely corresponds to the opening of the accommodating cavity 13 of the filter core assembly, the air permeability is maximum, and therefore all air amounts are clean gas with the fragrance of the first fragrance 14;

[0049] When the air inlet amount is greater than the minimum value and less than the maximum value, the air pressure generated in the air inlet cavity and the air cylinder upper cavity drives the piston 51 to move downward against the elastic force of the reset spring 54, and through the linkage of the first connecting rod 61, the second connecting rod 62, the third connecting rod 63 and the fourth connecting rod 64, drives the movable frame 32 to slide in the sliding groove 67, so that the overlapping area of the air vent of the adjusting plate 3 and the opening of the accommodating cavity 13 of the filter core assembly is reduced, thereby changing the air permeability and reducing the fragrance volatilization.

[0050] When the air inlet amount is the maximum value, the air vent of the adjusting plate 3 is completely misaligned with the opening of the accommodating cavity 13 of the filter core assembly, the air permeability is minimum, and therefore the air outlet gas is all odorless clean gas blown out from the air outlet surface 11.

[0051] The filter of the embodiment further comprises an outer frame 2; the outer frame 2 is provided with a placing groove 21 for placing the filter core assembly; the top of the outer frame 2 is rotatably provided with a plurality of elastic sheets 22.
